问题描述

大家好，

我的表单上有两个图像，一个是.jpg，另一个是.png.我正在做的就是覆盖它们，以尝试创建一张图像，然后将其保存到文件中.我在网上做了很多搜索，但似乎找不到简单的方法来做.我有下面的代码，我认为这两个代码已合并为MyImage.然后如何将其保存到.jpg文件?

另外，有人知道这样做的好方法吗?

Hi all,

I have two images on my form, one is a .jpg the other is a .png. What I''m doing is overlaying them to try and create one image that I can then save to a file. I''ve done a lot of searching on the net but can''t seem to find a simple way to do it. I''ve got the code below which I think has amalgamated the two images into MyImage. How can I then save this to a .jpg file?

Alternativelyy, does anyone know of a nice easy way to do this?

public static void Overlay(ImageSource first, ImageSource second)
  {

   ((BitmapFrame)first).Decoder.ToString();

   var group = new DrawingGroup();
   group.Children.Add(new ImageDrawing(new BitmapImage(new Uri(((BitmapFrame)first).Decoder.ToString(), UriKind.Absolute)),
    new Rect(0, 0, first.Width, first.Height)));
   group.Children.Add(new ImageDrawing(new BitmapImage(new Uri(((BitmapFrame)second).Decoder.ToString(), UriKind.Absolute)),
    new Rect(0, 0, first.Width, first.Height)));

   Image MyImage = new Image();

   MyImage.Source = new DrawingImage(group);

  }

谢谢大家，
